N. Korea ready to make another nuke test anytime: S. Korean envoy

SEOUL, Oct. 15 (Yonhap) -- North Korea has "very serious nuclear capabilities" and it is able to conduct another round of nuclear tests "any time," South Korea's nuclear envoy said Tuesday.

The communist country has restarted a nuclear reactor at its Yongbyon nuclear center, a provocative move that would provide Pyongyang with enough plutonium to build one atomic bomb a year, according to Seoul's spy agency.
